Abstract:
Illegal wild animal trade and possession represents a threat to One Health due to the pathogens exchange between wild animals and humans. We report the detection and genomic characterization of a multidrug-resistant (MDR) Escherichia coli strain (MP02) colonizing a capuchin monkey (Sapajus sp.) rescued from illegal possession. MP02 exhibited ExPEC-related genes, harbored an IncHI2-ST1 plasmid composed of quinolones, aminoglycosides, and sulfonamides resistance genes, besides the extended-spectrum β-lactamase (ESBL)-encoding gene blaCTX-M-15 located in a conserved Tn3-like transposon. To the author's knowledge, this is the first report and genomic analysis of a MDR bacterium isolated from an illegally traded non-human primate.
